Miniaturized board card structure powered by multichannel isolation group

The invention discloses a miniaturized board card structure powered by a multichannel isolation group. The miniaturized board card structure comprises a PCB main body, the processor is connected with the PCB main body; the processor comprises an ARM (Advanced RISC Machines) chip; a plurality of isolation groups, wherein the plurality of isolation groups are connected with the PCB main body; each isolation group comprises a plurality of functional elements which are packaged to form an integral structure; each isolation group is connected with an isolation power supply module; and each processor connection interface included in each isolation group is connected with the processor through a digital isolator. The structure is simple and reasonable, the size of the board card is reduced under the condition that the isolation effect is not influenced, and the structure is more suitable for the use scene of small equipment. The number of the isolation groups is kept, convenience is provided for expansion of the who
